AC Milan will score at least 2 goals, or a refund, or a win based on goals scored, or you can take Total Over 2.5, since AC Milan's games practically always have Total Over 2.5, with Juventus and Atalanta closing in.
Villarreal will fight to avenge their latest defeat; motivation is high, and they need to reach the European competition places, as they have to complete all their home tasks before reaching the Europa League. I also think they will win on shots on target.
